Transport within Singapore is mainly land-based. Many parts of Singapore are accessible by road, including islands such as Sentosa and Jurong Island. The other major form of transportation within Singapore is rail: the Mass Rapid Transit which runs the length and width of Singapore, and the Light Rail Transit which runs within a few neighbourhoods. The main island of Singapore is connected to the other islands by ferryboat services.

Before World War II, rickshaws were an important part of urban public transportation. Rickshaws were taken over by the trishaw after the world war. The Trishaw has been discontinued for usage as a means of transportation after 1980. However, there are some trishaws left which now serve as tourist attractions, taking tourists for a ride around the downtown district for a unique Singapore experience.

The 10 expressways completed, plus the 3 semi-expressways in Singapore.

The planning, construction and maintenance of the road network is overseen by the Land Transport Authority (LTA), and this extends to expressways in Singapore. These form key transport arteries between the distinct towns and regional centres as laid out in Singapore's urban planning, with the main purpose of allowing vehicles to travel from satellite towns to the city centre and vice versa in the shortest possible distance. These expressways include:

The influence of expressways on Singapore's transport policy developed shortly after independence during the history of Singapore because of frequent traffic congestion in the Central district. The aim was to encourage residential development in other parts of the island and give residents in these new "satellite towns" a convenient link between their homes and their workplaces (which were mostly situated around the city centre.)

Singapore's only cable car system, the Singapore Cable Car, plies between Mount Faber on the main island of Singapore and the resort island of Sentosa as an alternative means of accessing that tourist attraction. The cable car system underwent a revamp that was completed in August 2010.

The Bus, MRT, LRT and taxi system make up the public transport system in Singapore.

Public transport covers a variety of transport modes such as bus, rail and taxi. This is a result of great emphasis by the Government of Singapore to promote its use over private transport. About 5.308 million trips are made on a daily basis on the public transport system and at least half of its population utilises it daily.

The public transport system is the most important means of transportation to work and school for Singaporeans. About 52.4% of Singaporean residents (excluding foreigners) go to work using public transport according to the Singapore Census of Population 2000, with 41.6% using private transport and the remaining 6.1% not requiring any form of transport. Amongst school-going residents, 41.5% of them go to school by public transport, 24.9% by private transport, and a further 30.1% do not require any form of transport at all.

A slight dip has been noted in the number of Singaporeans and permanent residents using public transport compared to 1990, which had 55.0% and 46.3% of them going to work and to school respectively. The government aims to reverse this trend such that the total average number of commuters on public transport rises above 75% of all trips made.[1]

The public transport system is regulated by the Land Transport Authority, which oversees the three main modes of public transportation. Fare regulation and bus service standards are under the purview of an independent body, the Public Transport Council, while TransitLink, established by SBS Transit, SMRT Trains and SMRT Buses, helps to create an integrated multi-modal system with a common fare-payment mode, information platform, and a physical network without duplication of services.

The policies of the Land Transport Authority are meant to encourage the use of public transport in Singapore. The key aims are to provide an incentive to reside away from the Central district, as well as to reduce air pollution. Singapore has a Mass Rapid Transit (MRT) and Light Rail Transit (LRT) rail system consisting of five lines. There is also a system of bus routes throughout the island, most of which have air conditioning units installed due to Singapore's tropical climate. Buses without air conditioning installed are gradually being phased out. A contactless smart card called the EZ-Link card is used to pay bus and MRT fares.

Launched in December 2007 by Land Transport Authority, Singapore Tourism Board and EZ-Link, the Singapore Tourist Pass[9] offers unlimited travel for tourists to Singapore on Singapore's public transport system. For $8 a day, tourists can take any number of rides on buses and trains operated by SBS Transit, SMRT Buses and SMRT Trains. Certain buses like Night Rider are not applicable. The Singapore Tourist Pass is available at selected MRT stations.

The international railway line to Malaysia is an extension of the Malaysian rail network operated by Keretapi Tanah Melayu (Malayan Railways). Since 1 July 2011, Woodlands Train Checkpoint serves as the southern terminus of the KTM rail network. Previously, KTM trains terminated at Tanjong Pagar railway station in central Singapore. The presence of the railway line was a source of contention between the two countries until the relocation was agreed. The new MRT link between Woodlands North and Tanjung Puteri, is expected to be built by 2020 to increase traffic.

The Port of Singapore, run by the port operators PSA International (formerly the Port of Singapore Authority) and Jurong Port, is the world's busiest in terms of shipping tonnage handled 1.04 billion gross tons were handled in the year 2004, crossing the one billion mark for the first time in Singapore's maritime history. Singapore also emerged as the top port in terms of cargo tonnage handled with 393 million tonnes of cargo in the same year, beating the Port of Rotterdam for the first time in the process. In 2006, it handled a total of 448 million tonnes of cargo.[10]

Singapore is ranked second globally in terms of containerised traffic, with 21.3 million Twenty-Foot Equivalent Units (TEUs) handled in 2004,[11] and is also the world's busiest hub for transshipment traffic. Additionally, Singapore is the world's largest bunkering hub, with 23.6 million tonnes sold in 2004.[12]

In 2007, the Port of Singapore is ranked the world's busiest port once again, surpassing Hong Kong and Shanghai.[13] The Port of Singapore is also ranked the Best Seaport in Asia.

Singapore aims to be Asia's aviation hub chiefly via the promotion of liberal aviation policies in a bid to encourage airlines to commence and maintain operations there. The aviation industry is regulated by the Civil Aviation Authority of Singapore, a statutory board of the Singapore government under the Ministry of Transport.

An open skies agreement was concluded with the United Kingdom in October 2007 permitting unrestricted services from Singapore by UK carriers. Singapore carriers were allowed to operate domestic UK services as well as services beyond London Heathrow to a number of destinations, including the United States along with Canada.[14]

There are six local scheduled service airlines, all of them operating from Singapore Changi Airport, offering scheduled flights to over 70 cities on six continents. The national flag carrier, Singapore Airlines, operates from Changi Airport Terminal 2 and 3. Its subsidiaries, SilkAir and Scoot, operate from Changi Airport Terminal 2.

Singapore's two budget airlines, Jetstar Asia Airways and Valuair, operate from Changi Airport Terminal 1. Only one budget airline, Tiger Airways, chose to operate at the Budget Terminal; other budget airlines have cited various reasons for not shifting operations to the Budget Terminal, including accessibility and ease of transfers to connecting flights.

Tiger Airways Singapore now operates from Changi Airport Terminal 2 due to the demolishment of the Budget Terminal for the future Terminal 4, since 2012.

Singapore Changi Airport, with its three terminals, is one of the most important air hubs in the region. The international airport is situated at the easternmost tip of the main island, and serves 185 cities in 58 countries.[15] With the recent opening of the third terminal, Changi is now capable of handling 64 million passengers every year.
